Flame Spray Gun

What is a Flame Spray Gun?

Flame Spray Gun is mostly used to apply abrasive coatings or nickel/chrome self-fluxing alloys, which are then heat treated to metallurgically bond to the substrate. Flame Spray Gun is extremely versatile and provides a premium coating for wear resistance, corrosion protection, thermal and electrical insulation, and other properties that have long been the ultimate goal of all coating processes. The system can be programmed or made fully automatic.


The heavy-duty Thermal Spray Gun is used successfully with varying spray rates up to 25 Kg/hr, which reduces spray time on large parts. that deposits various metals, ceramics, cermets, and other powdered materials The powder is gravity fed into the nozzle system from the hopper at the top of the gun, where it is melted by an oxy-acetylene gas flame and spray deposited on the substrate surface. 

Fused coatings are widely used in high wear applications such as mining and steel to prevent roll, piston, and other equipment wear in aggressive wear environments. A Zinc Spray Gun creates a flame with oxygen and fuel gasses into which powder is injected. To make the coating, molten powder particles are projected onto the workpiece. Many of the coatings sprayed by this method are then heat treated at around 1000oC to 'fuse' them to the substrate surface. 


This process produces hard, corrosion-resistant fused coatings that can withstand wear from abrasion, fretting, cavitation, and other hard surfaces. They can be applied 1 - 5 mm thick, significantly thicker than hardware coatings applied via plasma or HVOF Gun. When different proportions of carbon, silicon, and boron are added to the basic nickel/chromium alloy, hard phases of carbides, silicides, and borides form. 

Using an oxy-fuel gas flame, a flame spraying gun is used for thermal spraying powder. A gas mixture system based on the injector principle ensures function and safety. The flame spraying gun includes a shut-off valve that allows you to open and close the gas flow without changing the adjustment. Acetylene, propane, hydrogen in combination with oxygen, and compressed air for cooling can all be used as fuel gasses.

Working Process of Flame Spray Gun

Wire Flame Spray Gun is a thermal spray coating process that produces high-quality surface coatings by melting a spray coating material and propelling it onto a substrate using heat generated by the combustion of a fuel gas with oxygen. The heat generated by the combustion of fuel gas, usually acetylene or propane with oxygen, is used to melt the spray coating material in flame spraying. A consumable, usually a powder or wire, is heated and propelled onto a substrate to form a surface coating in this process.

Flame spray coating is an umbrella term for various thermal spray processes using Babbitt Wire, Aluminum Wire, and Zinc Metalizing Wire. A high-temperature flame, as the name implies, converts the coating materials into a semi-molten state; this molten material is then sprayed onto the workpiece to form a surface coating. Our company can create flame spray coatings for all industries and applications by varying the levels of heat and kinetic energy involved. We can easily meet the porosity, bond strength, and oxide content requirements of your application.

To achieve better properties we recommend using Acoustic Chamber, HVOF coating material is heated and accelerated by a gas stream to the surface of a component, as with all thermal spray coating processes. The gas stream is created using the HVOF coating process by mixing and igniting oxygen and fuel in a combustion chamber and allowing the high-pressure gas to accelerate through a nozzle. A powder is introduced into this stream, where it is heated and accelerated towards the surface of a component. The final thermal spray coating is made up of thin overlapping platelets.

Applications of Flame Spray Gun

Flame spraying is commonly used where lower coating costs and less stringent coating quality requirements are desired. The process is widely used to reclaim worn or mismatched parts, as well as to deposit zinc and aluminum coatings on steel structures to protect them from corrosion. It is also used to apply wear-resistant nickel or cobalt base alloy coatings.

These are some applications of Flame Spray Gun:-

  1. Aluminum or zinc wire coatings are used to protect structures and components from corrosion, for example, bridges, offshore platforms, and LPG bottles. Although more expensive, aluminum is resistant to acidic gaseous atmospheres.

  2. Flame spraying with Thermal Spray Wire is also employed in the application of corrosion-resistant thermoplastic polymer coatings. Salt water and other neutral solutions Alkaline corrosion is not a problem for zinc. 

  3. Reclaiming worn shafts, especially bearing areas, with materials such as stainless steel or bronze alloys. Because the coatings produced are porous, lubricants can be absorbed into the coating, improving the bearing's performance with Powder Flame Spray Gun.

  4. Metallurgically bonded, fully dense coating Glass plungers are a good example of an application where a spray-fused coating is used to protect against the molten glass at temperatures approaching 700°C.
